1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

It has been known for a long time that infection of cultured cells with poliovirus results in the overall inhibition of transcription of most host genes. We examined whether selected host genes can escape transcriptional inhibition by thiouridine marking newly synthesized host mRNAs during viral infection. Using cDNA microarrays hybridized to cDNAs made from thiolated mRNAs, a small set of host transcripts was identified and their expression verified by quantitative PCR and Northern and Western blot analyses. These transcripts were synthesized from genes that displayed enrichment for NF-κB binding sites in their promoter regions, suggesting that some NF-κB-regulated promoters can escape the virus-induced inhibition of transcription. In particular, two negative regulators of NF-κB, IκBa and A20, were upregulated during viral infection. Depletion of A20 enhanced viral RNA abundance and viral yield, arguing that cells respond to virus infection by counteracting NF-κB-induced proviral effects.
